The present invention is related to the following commonly assigned and co-pending U.S. applications:
"Method Of Displaying A Product Restriction Message By An Electronic Price Label", filed Oct. 7, 1986 invented by Goodwin, and having a Ser. No. 08/726,595 and
"Method Of Displaying A Promotional Message By An Electronic Price Label", filed Oct. 7, 1996 invented by Goodwin, and having a Ser. No. 08/726,596.
The present invention relates to electronic signage, and more specifically to a method of displaying a government program message by an electronic price label (EPL).
EPL systems typically include a plurality of EPLs for each merchandise item in a store. EPLs typically display the price of corresponding merchandise items on store shelves and are typically attached to a rail along the leading edge of the shelves. A store may contain thousands of EPLs to display the prices of the merchandise items. The EPLs are coupled to a central server from where information about the EPLs is typically maintained in an EPL data file. Price information displayed by the EPLs is obtained from the PLU file.
To identify items eligible for government subsistence programs, such as the food stamp program and the women with infant children (WIC) program, EPL systems use paper shelf talkers or bibs. However, these shelf talkers must be installed manually, thereby increasing the cost and setup time associated with special programs.
Therefore, it would be desirable to provide a method of displaying a government program message by an EPL that avoids the use of paper shelf talkers.
In accordance with the teachings of the present invention, a method of displaying a government program message by an electronic price label (EPL) is provided.
A method of displaying a government program message by an electronic price label (EPL) includes the steps of storing the government program message with a government program indicator associated with the government program message in a first location, storing the government program indicator in a second location, creating a control message addressed to the EPL including the substeps of reading the government program indicator for the EPL from the second location and reading the government program message from the first location, transmitting the control message to the EPL, receiving the control message by the EPL, and displaying the government program message by the EPL.
The second location may be a price look-up (PLU) file in which the government program indicator is stored within the record of the item. The second location may also be an EPL data file in which the government program indicator is stored within a record of the EPL. In the latter case, the government program indicator may be copied from the PLU file to the EPL data file.
It is accordingly an object of the present invention to provide a method of displaying a government program message by an EPL.
It is another object of the present invention to provide a method of displaying a government program message by an EPL that makes paper shelf talkers unnecessary.
It is another object of the present invention to provide a method of displaying a government program message by an EPL that displays special text or graphics.
It is another object of the present invention to provide a method of displaying a government program message by an EPL that makes use of a government program indicator in a price look-up file.
Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from the subsequent description of the preferred embodiments and the appended claims, taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a block diagram of a store system;
FIG. 2 is a perspective view of an EPL displaying a government program message; and
FIG. 3 is a flow diagram illustrating a method of displaying a government program message.
Referring now to FIG. 1, store system 10 includes electronic price label (EPL) computer 12 and EPL 14. EPL computer 12 and EPL 14 may communicate with each other using wireless communication, cable communication, or a combination of both.
EPL computer 12 records, schedules, and transmits all messages to EPL 14 and analyzes status messages from EPL 14. Messages from EPL computer 12 include price change messages and diagnostic messages.
EPL computer 12 transmits a message containing a government program message from EPL government program data file 28.
Government program data within EPL government program data file 28 includes government program messages and a government program indicator which uniquely identifies each government program message. Government program messages identify items eligible for purchase under special government programs, such as the food stamp program and women with infant children (WIC) program. Government program messages may include text and/or special graphic images. Such items have traditionally been identified using paper shelf talkers. Control circuit 16 may display price separately, or as an integral part of a government program message. The government program messages and government program indicators are arranged as a table in EPL government program data file, such as the one shown below as Table I.
TABLE I______________________________________Indicator Government Program Message______________________________________00 (No message)01 FS (Food Stamps)02 WIC (Women with infant children)03 (both message 01 and message 02 displayed)______________________________________
EPL computer 12 maintains and uses EPL data file 26, which contains item information, identification information, item price verifier information, and status information for EPL 14 and other EPLs within system 10.
Storage medium 24 stores EPL data file 26 and EPL government program data file 28.
EPL 14 is one of many EPLs within system 10. EPL 14 includes control circuit 16, memory 20, and display 22.
Control circuit 16 controls the internal operation of EPL 14. Control circuit 16 stores received messages from EPL computer 12 and transmits response messages to EPL computer 12. Control circuit 16 also controls the display of price and government program messages, including blinking.
Upon receiving a message containing a government program message, control circuit 16 stores the government program message in memory 20 and displays the government program message using display 22.
Memory 20 stores government program messages and other data necessary for the proper operation of system 10.
Display 22 displays price and government program messages. Display 22 is preferably a liquid crystal display (LCD).
Transaction server 32 is a host to a plurality of transaction terminals and its primary function is to provide price and item information to the transaction terminals from a price look-up (PLU) file 36. Transaction server 32 and EPL computer 12 may also be one computer.
Under the method of the present invention, PLU file 36 also contains government program indicators for preselected items. Government program indicators may be added to PLU file 36 by an operator using input device 30. Input device 30 may be a keyboard or other suitable input device.
Storage medium 34 contains PLU file 36.
Turning now to FIG. 2, EPL 14 is shown in more detail. The government program message 38 identified by government program indicator "03" in Table 1 is shown, and identifies the item as being eligible under the food stamp and WIC programs. Both messages associated with government program indicators "01" and "02" are displayed at the same time.
Turning now to FIG. 3, a method of displaying government program messages begins with START 40.
In step 42, EPL government program data is stored within EPL government program data file 28.
In step 44, input device 30 records a government program indicator entered for an item by an operator.
In step 46, transaction server 32 stores the government program indicator in the item's record in PLU file 36.
In step 48, EPL computer 12 reads PLU file 36 and obtains the government program indicator.
In step 50, EPL computer 12 stores the government program indicator in EPL data file 26.
In step 52, EPL computer 12 creates a message for EPL 14 by reading the government program indicator in EPL data file 26. EPL computer 12 obtains a government program message corresponding to the item's government program indicator from EPL government program data file 28.
In step 54, EPL computer 12 transmits the message addressed to EPL 14.
In step 56, EPL 14 receives and acknowledges the message.
In step 58, control circuit 16 stores the government program message in memory 20.
In step 60, control circuit 16 causes display 22 to display the government program message associated with the government program indicator.
In step 62, the method ends.
